IMPRQMEME NT IN GANG-FLOWS.

Specification iiorn ing part of Letters Batent No. 195,49 8, datedSeptember 25, 1877 application filed July 30, 1877.

To. all whom it may concern Be it known that 1;,DAN12EL FUNK, of

Harrisburg, county of Lin and State of Oregon, have'invented a new andImproved Gang- Plow, of'wh-i-ch the following is a specification:

Figure 1 is a top yiew of my improved machine. Fig. 2" is a side viewof" the same,

partly in section, through the. line as as, Fig.1.

Similar letters of reference indicate cor-re. sponding parts.

The object of this invention is to:- furnish an improved gang-plow,which shall; be. so constructed that it may be adjusted towork at anydesired depth in the ground, which may have the pitch of the plowschanged as hard and soft places occur without having its adjustmentchanged, which will enable the plows to be readily raised from .theground for convenience in passing from place to place, which will alloweach plow to rise independently of the others to pass obstructions, andwhich shall be simple in construction, readily controlled, and may turnasquare corner without having the plows raised from the ground.

The invention consists in the combination of the forwardly projectingbar, the rearwardly-projectin g bar, the cross-bar, the swiveled screws,and the lead-bar with each other,

and with the wheels and axle for connecting the plow-beams with saidwheels and axle; in the combination of the straps, the pivoted blocks,and the pivoted bars with the leadbar and with the plowbeams, to enablethe pitch of the plows to be temporarily changed without changing theposition of the lead-bar; in the combination of the shaft, the chains,and the lever and catch-bar with the plow-beams, the pivoted bar, andthe lead-bar; and in the combination of the shaft and pulleys, thechains, and the lever and catch-plate with the plow-beams, the frame,and the axle, as hereinafter fully described.

Inthe drawing, AA are the wheels, which revolve upon the journals of theaxle B. To the axle B, near one end, is attached the rear end of a bar,'0. To the axle B, near its other end, is attached the foward end of abar, D. The forward ends of the bars 0 D are connected by an angularbar, E.

If desired, the bar D may project as far forward as the bar 0, and thebar E may be straight.

To, the forward end of the bar 0, and to the bar D, at a suitabledistance in the rear of the axle B, are swiveled two crank-screws, E,which pass through holes in the ends of the leadhar G, so that the. saidlead-bar G may be raised and lowered by turning the said crankscrews Fto adjust the plows to work at any desired depth in the ground. Thelower ends of the screws F work in. holes in the free ends of the bracesf, the other ends of which are attached to the bars 0 D. To the upperand lower sides of the lead-bar G are attached four (more or less) pairsof straps, H, the rear ends of which project, and to and between themare pivoted the blocks I, so that the plows may have a free lateralmovement.

J J are short bars, the forward ends of which are notched to receive theblocks I, and are pivoted to said blocks. The rear ends of the bars Jare notched to receive the forward ends of the beams K, and are pivotedto said beams. The forward ends of the beams K and the bottoms of thenotches in the bars J are beveled, to prevent the said beams K fromdropping below a straight line with said bars J. The rear parts of thebeams K are curved downward, and to their ends are attached the plows L.To the forward ends of the beams K, at or near their pivots, areattached the lower ends of the short chains M, the upper ends of whichare attached to a shaft, N. The ends of the shaft N work in supports 0,attached to the lead-bar G, and to said shaft is attached the end of ashort chain, P, the other end of which is attached to a lever, Q. Thelower end of the lever Q is pivoted to the lead-bar G, or to asupportattached to said bar. The lever Q moves along the notched edge of anarched plate, R, by which it is held in any position into which it maybe adjusted. The ends of the notched catch-plate R are attached to thelead-bar G, or to a support attached to said bar.

By this construction, by operating the lever Q the forward ends of theplow-beams K may be raised and lowered to change the pitch of the plowsas hard or loose soil is encountered in crossing the field.

To the rear parts of the plow-beams K are attached the lower ends of theshort chains S, the upper ends of which are attached to the pulleys orsegments of pulleys T, which are attached to the shaft U. The journalsof the shaft U revolve in hearings in the supports V, the rear one ofwhich is attached to the rear end of the bar D. The forward support V isattached to the axle B.or to the rear end of the bar 0. To one of thepulleys T is attached the end of a chain, W, the other end of which isattached to the lever X. The lever X moves along the notched edge of thearched plate Y, and its lower end is pivoted to the axle B, or to asupport attached to said axle. The ends of the catch-plate Y areattached to the axle B, or to a support attached to said axle.

By this construction, by or eratin g the lever Xthe plows can be raisedfrom the ground, when desired, for convenience in passing from place toplace.

The plow-beams K are connected and held at the proper distance apart bythe rods or bars Z, the ends of which are connected with, and slide upand down upon, long keepers A, attached to the said beams K, so thateach beam K can move up and down freely while being kept in properposition laterally.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination of the forwardlyprojectingbar 0, the rearwardly-projecting bar D, the cross-bar E, the swiveledscrews F, and the lead-bar G with each other and with the wheels andaxle A B for connecting the plowbeams with said wheels and axle,substantially as herein shown and described.

2. The combination of the straps H, the pivoted blocks 1, and thepivoted bars J with the lead-bar G and with the beams K, to enable thepitch of the plows to be temporarily changed without changing theposition of the lead-bar G, substantially as herein shown and described.

3. The combination of the shaftN, the chains M and P, and the lever andcatch-plate Q R with the plow-beams K, the pivoted bars J, and thelead-bar G, substantially as herein shown and described.

4. The combination of the shaft and pulleys U T, the chains S and W, andthe lever and catch-plate X Y with the plow-beams K, the frame 0 D it,and the axle B, substantially as herein shown and described.
